1. A method for precision winding a rotor comprising the steps of:

  • providing a magnetic core with axially spaced ends and an insulator at each core end;

    providing a plurality of radially spaced notches in each insulator;

    wrapping a plurality of nonoverlapping turns of a wire lengthwise directly about the core and over each of the insulators at the core ends by guiding each turn of a plurality of turns of the wire into a plurality of the notches to define a first layer of turns with valleys between adjacent turns, each valley having a width less than the diameter of the wire; and

    wrapping a second layer of nonoverlapping turns about the core and over each of the insulators at the core ends and guiding the wire into the valleys between adjacent first layer turns,whereby the reception of the turns making up the first layer in the notches and the turns making up the second layer in the valleys maintains the first and second layers in fixed position relative to each other and to the magnetic core and the turns are precisely located on the rotor by reason of the wire being wrapped directly on the rotor.
